KVM, Kernel-based Virtual Machine, is a hypervisor built into the Linux kernel. It is similar to Xen in purpose but much simpler to get running.
Unlike native QEMU, which uses emulation, KVM is a special operating mode of QEMU that uses CPU extensions (HVM) for virtualization via a kernel module.
Verify if your CPU supports hardware virtualization
The following should return a valid flag for each CPU-Thread which confirm, that hardware virtualisation is enabled:
egrep '(vmx|svm)' --color=always /proc/cpuinfo |
You have no result. You may need to enable virtualization support in your BIOS.
Insall required packages for KVM:
zypper in kvm libvirt libvirt-python qemu virt-manager |
Add libvirtd to system autostart:
systemctl enable libvirtd.service |
… and start the libvirt daemon:
systemctl start libvirtd.service |
zypper in bridge-utils |
